High efficiency video coding (HEVC) is a video compression standard that outperforms the predecessor H.264/AVC by doubling the compression efficiency. To enhance the compression accuracy, the partition sizes ranging is from 4x4 to 64x64 in HEVC. However, the manifold partition sizes dramatically increase the encoding complexity. This paper proposes a fast depth decision based on spatial and temporal correlation. Spatial correlation utilize the code tree unit (CTU) Splitting information and… 
Multi-feature based fast depth decision in HEVC inter prediction for VLSI implementation
This paper proposes a hardware friendly fast depth range definition algorithm based on multiple features that can saved about 33.72% of the processing time with 0.76% of BD-bitrate increase on average.


Comparison of the Coding Efficiency of Video Coding Standards—Including High Efficiency Video Coding (HEVC)
The results of subjective tests for WVGA and HD sequences indicate that HEVC encoders can achieve equivalent subjective reproduction quality as encoder that conform to H.264/MPEG-4 AVC when using approximately 50% less bit rate on average.
